(Fig. 3)

Specimens studied. 30 SpecimenS frOm Pterygoplichthys ambrosettii frOm the Aguapeí RiVer: 10 VOucherS in CHIOC (38843a, b; 38844,–38849; 38850a, b), 15 VOucherS in CHIBB (252–266L) and 5 VOucherS in IPCAS (M- 653).

Type host. Hypostomus plecostomus (LinnaeuS) ( SilurifOrmeS: LOricariidae).

Additional host. Pterygoplichthys ambrosettii (HOlmberg) ( SilurifOrmeS: LOricariidae) (neW hOSt recOrd).

Site of infection. GillS.

Type locality. GuangzhOu, China.

Representative DNA sequence. 1,575 bp lOng Sequence Of the D1–D3 regiOn Of the lsr DNA Of One Specimen frOm P. ambrosettii (GenBank AcceSSiOn NO. MF 116372).

Remarks. Heteropriapulus simplex WaS deScribed frOm H. plecostomus intrOduced tO China frOm SOuth America (Li & Huang, 2012). SpecimenS fOund in P. ambrosettii differ Only Slightly, eSpecially in their SOmeWhat greater Size and a thicker dOrSal cOnnecting bar, frOm SpecimenS deScribed by Li & Huang (2012) frOm the type hOSt (Table 2). The preSent Study prOVideS a neW hOSt and geOgraphical recOrd fOr H. simplex, Which iS repOrted frOm the prObable Original diStributiOn area, i.e. NeOtrOpical RegiOn, fOr the firSt time.
